Chapter #3, Question #13: Consider the following data for total atmospheric column ozone measurements (as DU) at three locations around the Earth, obtained using the TOMS in 2001.   January 15 april 15 july 15 october 15 Tierra del fuego (Chilie, argentina) 323 261 339 206 Nairobi (Kenya) 234 273 266 (Aug. 15) 266 Kiev (Ukraine) 321 420 314 273   Assume that these are typical of values that might be obtained in any other year, and discuss the trends as you move down the columns and along the rows, in terms of your knowledge of stratospheric ozone behavior.

The use of solar power illustrates which of the following green chemistry principles? Design for less waste Design for energy efficiency Atom economy Design for less hazards Design using benign chemicals

Use the figure below to answer this question. Reflected Reflected by Reflected from earth's surface (4%) by clouds (20%) atmosphere (6%) V Absorbed by atmosphere (16%) Absorbed by clouds (3%) Absorbed by water, carried to clouds (23%) Absorbed by earth's surface (51%) What happens to incoming solar radiation? Radiated to space from clouds and atmosphere (64%) Radiation absorbed by atmosphere (15%) Convection (7%) Radiated to space from earth (6%) Most of it (>50%) is scattered by the atmosphere. Most of it (>50%) is reflected by the clouds. Most of it (>50%) is reflected from earth's surface. Most of it is absorbed by the earth and clouds in the lower atmosphere.

Question 11 please

2. In a Mars Direct mission, the astronauts would return home in an Earth Return Vehicle (ERV) fueled by     methane and oxygen produced from terrestrial hydrogen and Martian CO2     helium-3 extracted from the lunar surface     finely-ground Martian rocks accelerated by an electromagnetic mass driver     cheap, traditional kerosene fuel brought from Earth   We might go back to the Moon someday to mine the lunar surface for an energy resource called     methane     antimatter     hydrazene     helium-3

5. The car you have been driving has a posted fuel consumption of 10.0 L/100 km (city) and 7.1 L/100 km (highway) according to the EnerGuide information. Overall, your actual fuel consumption has averaged 10.5 L/100 km. a) Is this better or worse than the posted fuel consumption? b) Provide three reasons why your actual fuel consumption may be different from the posted consumption. c) List three ways in which you could improve your fuel consumption (other than buying a new carl).

Paragraph 5: Discuss Fractional Distillation of petroleum oil to give the chemical feedstock to make synthetic polymers for commercial use of products in our daily lives and discuss your personal thoughts on incresing US drilling in the Gulf of Mexico or in the Artic. Think about it, every time you go to the grocery store and get a plastic bag which immediately gets discarded. Include your thoughts on mandatory recycling in the US especially for schools, government buildings, etc.
